title: [Megaloblastic pancytopenia in a female patient with rheumatoid arthritis given methotrexate and amidopyrine simultaneously].
abstract: The paper is concerned with the development of megaloblastic pancytopenia in a female patient with grave rheumatoid arthritis. The patient had been given methotrexate (15 mg per week) for a long time, supplemented by amidopyrine (1.0 to 1.5 g/day). The author holds that the development of the above-indicated complication is provoked by both drugs interference into folate metabolism. It is concluded that caution should be taken as to the combined use of methotrexate with non-narcotic analgesic drugs, nonsteroidal anti-inflammatory agents and sulfanilamides.
